ROLLER-SKATE.

JZliiClE-ICATION fuming part of LettersPatent No. 326,151. dated-September 15, 1885.

Application filed April 4, 1885. (No model.)

Z all whom it may'concern:

Be it known that I, CHARLES D. RICE, a citizen of the United States, residing at Corry, in the county of Erie and State of Pennsylvania, have invented certain new and useful Im provements in Roller-Skates, of which the following is a specification, reference being had therein to'the accompanying drawings.

My invention has relation to certain im provements in roller-skate clamping and truck connecting devices; and it consists in the construction and novel arrangement of devices, whereby any side pressure upon one truck is transmitted to the other, and the clamping arms and lever are brought into a convenient position for adjustment by the wearer, and also by which the skate is adapted to receive boots of different sizes-for example, a wide sole and narrow heel, or a narrow sole and a large heck-as will be hereinafter more fully described, and specifically set forth in the claims.

In the accompanying drawings, Figure 1 is a side elevation of my improved skate with its clamping devices attached and its forward portion in vertical section. Fig. 2 isa bottom View of the same with the foot-clamps open, and its parallel rod partly broken away to show the spring-connection of the trucks. Fig. 3 is a. bottom viewof the foot-clamps closed and a horizontal section on line 3/ y of Fig. 1. Fig. 4isavertical-section on line at x of Fig. 1; and Fig.5 is a rear view of my improved skate with the rollers in section.

Like letters refer to like parts in all the figures.

In the drawings, A represents the footplate,- which can be'made of steel, or of any suitable material, and to the under side of which are secured the upper castings or bearing-plates, A, of the trucks, by screws a, passing through the foot-plate A into the lugs or pillars A of said castings A.

The front and rear trucks, B, are arranged to rock in opposite directions to each other, and are set wider apart at the bottom than at the top. Said trucks are provided withbroad disk-bearing surfaces b, that permit free play of the parts.

The three pillars A of the casting A form the points of a triangle, and fulfill adouble service. They act as braces and supports for the foot-plate A, and as guides for the footclamps to play between them. The lower portion of the casting A is provided with a screw-threaded pe'rforatiomA, and the upper portion is provided with an oil channel and chamber, A, in line with and immediately below the perforation a in the foot plate',to receive oil,&c., to lubricate the disk-bearings b.

The casting .B is provided with a slotted arm, B, in the upper portion thereof, to receive one end of a metal spring, 0, and a pin or rivet, b, is inserted in the upper portion of said arm to'keep the spring in place;

The lower portionof the casting B hasa perforation, B", to receive one end of the rod D before it enters the perforation A of the bearing-plate A. The-perforation B acts as journal-bearings for the roller-spindle F, and said bearings are provided with an oil chamher and chaunel,b",to lead the oil to the rollerspindle F. A

The flat metal spring 0 has its upper edge concave, and extends from one truck to the other, and beingsimply held in position by the slotted arms B and pins b, allows the trucks to yield laterally, as said spring 0 receives both a bending and a twisting strain.

The parallel rod D is located immediately below the fiat spring 0. It runs parallel with the foot-plate A until it enters the casting B of the trucks, where it takes a diagonally-upward course at both ends. Thetwo endsD are screw-threaded and pass through the trucks B, and are screwed into the perforation A until the casting B rests 1 against the shoulder D, formed upon the rod- D.

Midway of the parallel rod D is a clamp,D which is provided withaslot at its upper end, through which the metalsprin'g 0 passes, and is held firmlyin position by aclamping-screw, d, located on the side thereof. The clamp D straddles the parallel rod Dand forms a central brace for the spring. The rod D .does a treble serviceit unites the working parts of each truck, strengthens the entire skate, and also furnishes a clamping-point for the spring.

The heel and sole clamps E are located under the foot-plate A and are connected by sheet metal links E and E and the lever E. Said clamps E pass above the casting A, between the pillars A thereof, and the latter act as guides for said clamps, which extend beyond the sides of the foot-plate A, where their ends are inwardlybeveled, as at c. The link E is secured to the two forward clamps at one end by a pivot,e, while at the other end it is united to the lever E by apivot, a. One end of said lever is bent down to form a pendent handle, 6, by which it can be swung from against the forward portion of the spring 0 toward the pendent pin (L The lever E is also provided with an eccentric stud-pin, e, to enter one of the perforations e in one end of the metal link E to adjust the clamps to any size of shoes, and the opposite end is united to the two rear clamps by the pivot 6". By these means the two links E and E are drawn together by the lever E.

In Fig. 5 the roller-spindle F is shown as having a head,F, at one end, and at the other end it is screw-threaded at F to receiveathin nut, f, which is transversely perforated and held in position by a pin, f, passingthrough said perforations and spindle.

Oil poured through the perforations a in the foot-plate A will follow various channels leading to all the wearing-surfaces of the skate.

Having now fully described my invention, I claim- 1. In a roller-skate, the combination of the truck-bearing A, having a central oil-chamber, A, and pillars A and the truck B, formingtherewith a dislrbearing, b, the slotted arm B, and transverse pin 2), with the foot-plate A, spring 0, and parallel rod D, substantially as and for the purpose described.

2. In a roller-skate, the combination of the casting A, provided with pillars A and screw-threaded perforation A and the oilchamber A with the casting 13, provided with a slotted arm, B, rivet b, journal-bearings B and oil-channel b substantially as and for the purpose described.

3. In a roller-skate, the metal spring 0, in combination with the rod D, clamp D and casting B, provided with slotted arm, substantially as and for the purpose described.

4. In a roller-skate, the rod D, provided with upwardly-bent screw-threaded ends D, and shoulders D thereon, and the clamping device D", in combination with the spring 0, the two castings A and B, roller-spindle F, and foot-plate, substantially as and for the purpose described.

5. In a roller-skate, the combination of the four clamps E, provided with upright ends 6, links E and E, provided with perforations e, and lever E provided with eccentric studpin a", substantially as and for the purpose described.

6. In a roller-skate, the clamp E, metal links E, and E and lever E in combination with the foot-plate A, castings A, having pillars A trucks B, and rollers, substantially as and for the purpose described.

7. In a roller-skate, the foot-plate A, provided with perforations a at both ends there of, in combination with the castings A, and trucks B, provided with oil -channels A and If, substantially as and for the purpose deeribed.

In testimony whereof I aiiix my signature in presence of two witnesses.

CHARLES D. RICE.
